LM5156-Q1: Do we have PSR calculator for LM5156-Q1?

Hi Teams,

Do we have PSR calculator for LM5156-Q1?

What's the difference between PSR & Non-isolated? If I want to calculate the compensation specs, can I directly use Non-isolated calculator to design the 800V to 24V flyback converter? 

BRs,

Marsh

    Hi Marsh,

    Thanks for reaching out.

    For LM5156 we do not have a PSR calculator. In the calculator for LM5157, there is an option to choose PSR.

    You can also use the non- isolated calculator for the compensation values. Just make sure the ratio of the feedback resistors is the same in the non-isolated calculator and in the PSR design later.

    Best regards

    Moritz
